Letters Patent No. 99,7 53, dated February 15,1870.

IM?ROVBMENT IN WASH-BOILERS.

The Schedule referred to in these Letters Patent and making part of the same.

To whom it may concern.:

Be it known that I, CHARLES D. BLINN, of Port Huron, in the county of St. Clair, and State of Michigan, have invented a new and useful Improvement in Y Clothes-Cleaning Apparatus; and I do declare that the following is a true and' accurate description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, and being a part of this specification, in Vwhich-- Figure 1 is a vertical longitudinal section through the centre of the boiler and its attachments;

Figure 2 is a transverse section through the same; and v Figure 3 is a plan of the cradle and boiler.

Like letters indicate like parts in each figure.

The nature of this invention relates to an improvementin those devices known tis-automatic washboilers, wherein the cleansing ofthe fabrics is effected Y by forcing through thenicurrents of hot suds.

for turning the clothes which are laid therein in hori zontal folds, so that the folds will stand i-n a vertical position, allowing the water topass more freely down through them tothe bottom ofthe boiler through perforations in the 4cradle providedfor that purpose.

In the drawings- A represents a wash-boiler` of ordinary construction.

B is a cradle, of sheet-metal, constructed in the form shown, inserted within the boiler, perforated with one or more rows of holes, a, in its lowest part, said holes being disposed in the direction of its length.

The sides of the cradle are perforated with a row of holes, b, near the top. l

Handles, c, are attached to the cradle, for conveniently' handling it.

It will be noticed that the upper corners, d, of the cradle are turned outward and rest against the walls ofthe boiler, so as to leave a Water-space between the straight sides of the cradle and the adjacent walls of the boiler.

e are a pair of lugs or hooks, secured to the top of the 'boiler on the outside of either of its straight walls.

C is a bar or strip'of wood or other material, suspended by loops or cords f, from the lugs c, so that it will rest on top of the clothes at one side. v

' A cord, g, is attached to each cud of the bar, and is laid on the bottom ofthe cradle, with the fabrics to be cleansed resting on it, folded hat.

D is a cover, of less width than the boiler in which it is inserted, resting on the cradle. It has hinged to its upper side, near each end, the hook h, having a transverse socket at the end, which embraces the edge of the boiler and thus locks the cover in place.

The operation of the device is as follows: In the bottomof ,the boiler is placed a small quan tity of soapsliced thin. The `cradle is then placed in position and water filled in until it rises an inch or two above the bottom of the cradle. The barG is then suspended in place, as described. The clothing to be washed is then laid in the cradle, folded smoothly',

in layers. lhe loops f are then cast oli" from the lugs e. Then, by drawing on the cord g, the mass of clothes is turned until the folds or layers stand vertically. The cover is then inserted in the boiler and locked in place. Heat is now applied to the bottom of the boiler'. The water soon expands and rises in the spaces between the walls ot' the boiler and the sides of the cradle, when it pours through the holes b, over the upper surface of the mass.

By the expulsion of a portion of the water from below the cradle, a partial vacuum is formed in the bottom of theboiler, which causes the' water on the surface of the mass of clothing to he drawn down through it and the holes a of the cradle into the bottom ot' the boiler', carrying with it the dirt extracted from the clothes.

As the ebullition and circulation of the Water proceed, a. large portion of this dirt and iilth is again carried up by the water; but, as the holes 1J are not of suiiicient capacity, being of less area than the passageway between the sides of the cradle and walls of the boiler, to permit the passage "of the water through them as fast as it is forced up, a partof the water,

particularly the scum or froth, containingthe lighter' portions of the dirt extracted from the fabrics, overiows the cover and deposits thereon said dirt, while the remainder of the water, beingcomparatively clear, is forced through the holes b, and over the clothes, the circulation being continued as already described.

What I claim as my invention, and desire to secure by .Letters Patent, is

1. In automa-tic wash-boilers, the bar C, provided with loops f and cords g, operating as and for the purpose set forth. l

2.`Iu con'ibination with the bar G provided with loops fand cords' g, the cradle B provided with apertures a and l) and projecting cornersV j, when constructed and arranged to operate as and for the purpose set forth. l A

3. The wasb-,boiler above described, composed of the boiler A, the cradle B, the bar C, and the cover D, when each of said parts'is constructed and all are combined and arranged to operate as and for the 'purpose set forth.
